Designhinweise
Decouple each VDD pin with a 100nF ceramic capacitor placed as close to the pin as possible. Additionally, use a 4.7uF or larger bulk capacitor on the main power rail. The VDDA pin should be connected to VDD through a ferrite bead or low-pass filter to reduce noise on the analog supply. Ensure the VBAT pin is connected to a backup battery or tied to VDD if not used.
For the LQFP100 package, ensure proper solder pad design with a 0.5mm pitch. Use a 4-layer PCB with a solid ground plane for best EMC performance. Place the crystal oscillator (8 MHz) and its load capacitors close to the OSC_IN/OSC_OUT pins (PD0/PD1) to minimize parasitic capacitance and ensure stable oscillation. Keep high-speed traces away from the crystal and analog pins.
Do not leave the BOOT0 pin floating; tie it to ground through a 10k resistor for normal boot from Flash. Ensure the NRST pin has a 100nF capacitor to ground and a 10k pull-up resistor to VDD. When using the internal RC oscillator, note that its accuracy is ±1% over temperature, which may not be sufficient for CAN or USB communication; use an external crystal for these interfaces.
Compliance-Informationen
RoHS compliant per STMicroelectronics product page. Not AEC-Q100 qualified for standard version; automotive-grade variants (e.g., STM32F103VDT6TR) are available.
